摘要： A cast iron pipe surface-modified for preventing corrosion and a method of modifying the pipe surface for corrosion prevention. A corrosion preventive coating is formed on the surface of the iron material of the pipe. The corrosion preventive coating is made up of an aluminum alloy containing not less than 5 wt % but not more than 25 wt % of Mn, the remainder being Al, the aluminum alloy being such that the manganese is present as a supersaturated solid solution in an aluminum phase. The corrosion preventive coating is formed by thermally spraying a quenched aluminum alloy of the above noted composition onto the surface of the iron material of the pipe.

摘要： A twin-drum continuous casting apparatus for casting a metal sheet (4) by supplying molten metal (3) to a pouring basin formed by a pair of cooling drums (1) rotating in opposite directions, and side gates (2), to cool the molten metal (3) by contact with surfaces of the cooling drums (1), thereby forming a solidified shell. The cooling drum (1) is formed from a drum body (11) having shaft portions at opposite end portions, and a drum sleeve (10) fitted on an outer peripheral portion of the drum body (11). Also, means is provided for preventing various adverse influences due to differences in thermal expansion of constituent members of the drum body (11) during casting. Thus, the reliability of the apparatus is increased, and the quality of casting is improved.

摘要： A cooling liquid is injected into and supplied to a cooling tubular body along its inner periphery to form a cooling liquid layer flowing down the inner peripheral surface of the body while revolving. A molten metal is then injected into the cooling liquid layer from the inner peripheral side thereof to divide, rapidly cool and solidify the stream of molten metal with the cooling liquid layer and obtain a metal powder. Since the metal powder is continuously obtained upon flowing down the tubular body along with the cooling liquid, the liquid can be continuously removed from the powder by suitable means, and the power can be subsequently dried continuously.
摘要翻译： 将冷却液沿其内周部注入冷却管状体，并在冷却管体内部周边形成冷却液层，从而形成在旋转的状态下沿着身体的内周面流下的冷却液层。 然后将熔融金属从其内周侧注入到冷却液层中，以用冷却液层快速冷却和固化熔融金属流并获得金属粉末。 由于金属粉末与冷却液一起沿着管状物体下流连续地获得，所以可以通过合适的方法从粉末中连续除去液体，随后可以连续地干燥。
